MattJackson b454d100c6 Update profiles: fix data extraction offset 
Firmware payload was extracted 12 bytes too early — included handler
table pointers instead of actual microcode. Fixed by scanning for
function table position (VM address pattern) instead of magic offsets.

All 206 profiles regenerated. Cold boot firmware upload should now work.

MattJackson 85b38de4a7 Update profiles.json: 206 drives with complete data 
Generated by: profile generator --profiles sdf0.bin keys.json --drive-db drive_profiles.json
206 profiles (66 A + 140 B), all with identity from brute-force dictionary.
No manual merging. One tool, three inputs, complete output.

MattJackson 686bf91bb5 Update profiles.json: 206 drives 
New profile format includes all -verified fields:
- ld_microcode (base64): firmware payload for WRITE_BUFFER/MODE_SELECT
- hardware_register_a/b_cdb: pre-built 10-byte SCSI CDBs
- drive_nominal_speed_cdb: calibration SET_CD_SPEED
- speed_zone_table, speed_calc_table: operation speed constants
- unlock_init_value, unlock_response_size_minus_init
- drive_signature: per-drive unlock check

206 profiles (66 mt1959_a + 140 mt1959_b), 661KB.
Identity fields merged from drive database.
All 32 tests pass.

MattJackson c26b6f6819 Refactor: Chipset architecture, remove supported/status gatekeeping 
- PlatformType → Chipset enum (MediaTek, Renesas)
- unlock_mode + unlock_buf_id stored in profile, not derived from enum
- Removed ReadinessStatus, supported field, needs_flash — library is agnostic
- Removed DriveMatch/Flashable — if we have a profile, try unlock
- profiles.json: chipset + unlock_mode + unlock_buf_id, no program/supported
- mt1959.rs reads mode/buf_id from profile fields directly
- Tests: find_known_drive, find_unknown_drive

MattJackson ddcb614777 v0.1.2: 206 supported drives (was 141) 
Fixed firmware database unpacker offset bug — recovered 65 additional drives.
All code.files verified: identical code (676 bytes), variable data.
Signature at offset 0x35C confirmed correct for all 8 code sizes.

 mt1959_a (mode=1, buf=0x44): 65 drives
 mt1959_b (mode=2, buf=0x77): 141 drives
